So bloated, if still almost good. I having nothing major against it tbh.
The cast are probably what stop me from disliking 'This Is 40'. Paul Rudd (Pete) and Leslie Mann (Debbie) are likeable and more than competent in the lead roles, while John Lithgow (Oliver) and Albert Brooks (Larry) are strong additions to this 'Knocked Up' spin-off.
The story features interesting stuff and has, just about, respectable intentions, but man is it overly long. They could've made the exact same point but with 30-40 minutes worth of fat cut out. I didn't care enough about the characters to see them for as long as I did, in short.
As alluded to, the onscreen talent do keep it bubbling along at a minimal level and, also, the music is very good. It just didn't need to be so dragged out, in my opinion.
